Isn't that generally done by reading new papers that have been published AFTER they have been reviewed?

I don't think that's a good solution, because I'd rather have the best researchers doing research, rather than reviewing the papers of lesser researchers.
What I think we need to do is recognize that researching and reviewing research are not necessarily done by the best people. For instance there are subjects where I probably could never become a researcher, because I just don't for some reason come up with new ideas in those subjects, but I can understand the new ideas others come up. Hence, I could potentially be a decent reviewer in those subjects.
What could work would be a system where we have reviewer as a separate profession. Researchers submit papers to reviewers who review them and give feedback, and an overall rating which is digitally signed. When a paper is published (by whatever means--open access journal, the researcher's blog, whatever), the signed reviewer ratings can also be included.
Over time, reviewers would develop reputations with readers, and researchers would hire high reputation reviewers to review their papers, allowing the good reviewers to make reviewing their full time job.
When someone posts an unreviewed paper at arXiv.org, I'd expect that reviewers who have not built up reputations would review it for free, and publish their reviews. I'd expect sites would spring up specifically to host these reviews. It would be through these sites that new reviewers would built up their reputations to where researchers will start to pay them to get reviews.
Even startup founders competing in the fast-moving world of business seem to find time to read and give feedback on things that interest them. I don't think a shortage of people willing to review papers is going to be a problem, and if it is, it's a problem that could easily be solved by the prestigious open access journals requiring those submitting papers to set aside time to participate in the peer review process of others' papers
